GOVERNOR MECHANISM FOB INTERNAL-COMBUSTIDN ENGINES.

Application gfiled October 14, :1922. Serial No. 594,666.

To Ml whomvlt may concern:

Be it :known that I, Fmmols R. Hos rn'r- HER, a citizen of the United States, residing at Kokomo, in the county of Howard and ,Stateof Indian-a, have im e-nted certain new and useful improvements in Governor Mechdmislnsfor internal-Combustion Engines of whieh the following is .a specification.

This invention pertains to an improved and novel governing mechanism for internal combustion engines, and while it may be neadily utilized in connection with various types of combustion engines it is especially adapted for use in connection with Fordson tractors.

The prime object of the invention is .to provide simple, durable, economical and thonoughly eflici-en-t :centrifuga'lly operated means for operating the throttle valve of an internal I combustion engine.

further-object of the inyen t-ion is to so construct, locate and combine the novel operating parts of this governing device as to insure the proper and safe operation .of the throttle with respect to the speed of the engine.

The foregoing and such other objects .as

, y appear from the ensuing description are accomplished by the construction, arrangesment, combination and location of the parts hereinafter more fully described; illustrated in the accompanying drawings, and particularly pointed out in the claims appended hereto, it being understood that slight changes in the preciseform, proportions and minor details of construction may be readily resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming a part of this specification it will seen that:

Figuie .1 is .a transverse vertical section through the governor casing showing the novel means embodying my invention.

Fig. 2 is a detail elevation partly in section and showing the governorcasing broken away in part, and I I I Figure 3 isia dean-i1 showing a Fordson throttle block in section and the throttle operating connections and engine block in side elevation. I

Similar numerals of reference are employed to designate like parts in the several views of the drawings. I I

In the embodiment of this invention as illustrated, the numeral 1 indicates the upper section of the governor casing and 2 the lower section thereof, and fitted within the central portion of said casing are a :series of bronze bushings 4 and 5 respectively, f-onrning bearings for a shaft 6 centrally supported within the casing, said shaft having fixedly secured to its lowermost ,end va steel bevel gear wheel 7, adapted to engage (and mesh with a similar bevel gear wheel 8 fixedly :secured to one end ortion of a Fordson cam shaft 9, as clear y shown [in 1.

Suitably secured :to the upper end of section 1 of the casing is a standard Fordson commutator 1-0 to the inner face .of which is fixedly secured the contacts 11. The upper threaded end of the shaft 6 projects vertically through the upper end of section ,1, and is provided with a sleeve 12 having a lateral extension 13 to which extension is suitably supported .a roller 14 adapted to engage the inner face of the contacts, as the shaft 6 is caused to rotate, said sleeve 12 being retained in its proper position by :the securing nut 12. Fixedly secured to the shaft 6 within the ccasiingwith its lower face resting in contact with the roller :tlirust bearing 15 is a bracket casting 1.6 to which casting is pivotally secured at 17, a plurality of weights or balls 18 adapted to normally rest in contact with the recessed portion 19 formed around the lower end portion of said casting.

.Slidingly secured around the shaft 6 by a pin 20 which passes through ,saidishaft and disposed above the casting 19, (is a sleeve 21 provided with vertical slots 22 for the reception of the pin 20,821ldaSlBGV8 being formed at its lower end with an outwardly and downwardly extended member 23 provided with a curved recess 24 in its lower face at its outer-edge portion for the reception of the peripheral portion of the weights or ballsIS, Resting upon the upp'erend portion of the sleeve 21- is .the roller thrust bearing 25, and

loosely seated in contact. with said roller bearing is the block or collar 26., surrounding the shaft 6, and formed with a laterallyex tcnded pin 27, at each side'for engagement with the forked end portion of each eccentric arm 28, the said eccentric armsrbeing fixedly. secured to a shaft 29, which passes IOU through and is supported by section 1 of the I I I casing as shown in Fig.2. I I v I Fixed secured to the outer side portion of the casing at each side thereof is an upright stud or rod 30, and to-the upper end portionf. je'ach'=of said'studs or rods is rigidly seem d a suitable plate or bar 31 adapted to restin contact with the upper surface of the commutator 10 for-securely 6 retaining the same in its proper position on the topio'ffthelcasingp 1 v Rigidly secured to the outer side of the casing at one end 'thereof'is an upwardlyextended flat plate spring 32, witl1 its upper free end resting in contact with one of the :side faces of the governor arm or throttle regulating lever 33, to the upper 'end of 'whichjis connected one end of a connecting 'rdd 34,;theother end of said rod being "sejlc ured to one arm of a bell cranklever securedto the engine block 34: and to the otherar'm of said lever is connected one end of a rod36, the other endof the latter'being. secured to an arm 37 secured to the throttle-operating shaft 38, whi'chlatter is secured' to. thebutterfly throttle valve 39 fitted in the mixing chamber 4:0,and whereby the amount of fuel admitted'to the en- I v wardl -qmovementdof said-sleeve 21, which action of thesle'eve imparts a similarup and down movement to the collar26- and I 'epcentric} arms '28 thereby impartingfthe properba'ck and 'forth movement, to the throttlefcontrolling lever 33 as will be readily understood. l

. It will be seen thatascrew-threaded' pin 41, which is pressed through an opening formed throughthe-springplate 352, is provided withia suitablethumb 'nut 42, where by proper tension may be provided in order to regulate the" desired resistance of the 1 throttle cont-rolling lever with relation to the action of the governor weights. lt' will be perceived that the section 2 of the casing isprovided with an opening 43 "formed 'therethrough for the reception of ==-,'fs'uitable" bolts :for fixedly securing the "governor mechanism to the engine block.

The operationfof my novel governing me'c anism may be br1efly'des'cr1bed as'fol- 1oWs:"'

As-"theshaft 6 which carries the operat-'- 'in'g'fpart'si of the-governor is caused to re- "volve', the weights 18 carried by the fixed.

bracket casting and resting substantially'in "contact'withthe lowerface of the outwardly and downwardly} extended member 23 at-Qty .centri fugalforce thrown outwardly ana -upwardly thereby forci ngthe sleeve 21 0 "to move upwardly-on 'said'shaft, thus'ra'isface of" the outwardly and" comprising a 1 casing,v

.ing'the block or sleeve:26',' which; action raises the eccentric arm 28 and turns the shaft'29 which imparts a backward and forward movement to, the throttle regulating lever 33, through themedium of the con- *nectionsleadingfrom, saidglever 33 to the throttle valve 39.

It will be understood that the roller thrust bearlng 25 is adapted to carry the load of the working parts of the governor which'is' caused bythe tensi'onon the'spring plate32 which rests against the'lever 33and-by tightening the tensionon the spring causes the engine to run faster while'releasing't-he tension on said spring permits the engine to run slower thus when the engine falls below speed, the weights will fall, and with a a spring tension acting "against the weights,

saidweights will move downward, which action opens the throttle enough to revive the speed, to the speed required, since as the weights rise it causes the throttle to :close, and as theweights' drop the throttle is caused to open. Hence, it will be readily V evident, that my improved governor mechanism is readily "adapted toregulate the 'speed'fso that with the slightest variation inthe load it will open or close 'the throttle.

Having thus described my invention, what? I claim and desire to secure by Letters Patent is: 1 i V V a 1.
